mAP using osnet_x1_0 and resnet50 is weird

[a2082761]

Hello,
I just runned Get started code as below using pretrained model 'osnet_x1_0' and even 'resnet50' too.
However, the result was weird. mAP was just 3.9%.... and when I used resnet50, it was 2.xx%.
How can I increase mAP and can you check my source code which I just want to use pretrained model and I don't want to train dadaset.
Thanks.

I got the same results as you, but i think you could try load other weights to get better mAP
